TROLLEY-WIRE CLIP.

SPECIFICATION forming part of Letters Patent No. 541,969, dated July 2,1895.

. Application filed October 9, 1894. Serial No. 525,393. (No model.)

To all whom it may concern.-

Be it known that 1, FRED WM. HAEUSGEN, a subject of the Queen of Great Britain,residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Trolley-Wire Clips; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being hadoto the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates particularly to improvements in clips or supports for trolley wires, its object being to provide a support of such construction that the line wire may be quickly and firmly attached thereto and easily disengaged therefrom, and also that thejumping of the trolley away from the wire while passing the clip or support may be avoided thereby preventing arcing at this point.

To thatend my invention consists of a novel arrangement and combination of parts which will be more fully hereinafter described and pointed out in the claim.

In the drawings, Figure is an end elevation of my improved clip. Fig.2 is a side elevation of the same. Fig. 8 is a vertical transverse section of Fig.1 taken in the line 00 as. Fig. 4 is a detached perspective view of the elastic sheet-metal support, showing the apertured projections spread apart to admit the trolley-wire, and Fig. 5 is an under side view of the clamp.

Referring to the drawings it will be seen that the screw-threaded shank consists of the upper portion 1 adapted for engagement with the insulating bell or hanger secured to the supporting cross wire and the lower portion 2 which has a downwardly extending projection 3 of smaller diameter than-the shank and of smooth cylindrical configuration. Between the upper and lower screw-threaded portions 1 and 2 of the shank is the annular shoulder 4.. The support for the trolley wire 5 is formedof a strip of sheet-metal consisting of thetwo inclined sides 6, 6, the bend or channel 7 along which the trolley wire rests, the upper separate ends being bent inwardly to form projections 8, 8, provided with centrally arranged apertures 9, 9. (See Fig. 4.)

The wedge-shaped clamp 10, which, when in position, rests between the inclined sides 6,6, of the support, tapers downwardly at the sides 11, 11, which have contact with the inclined sides of the support and along its lower edge is formed the groove 12 which has contact with the upper surface of the trolley wire. This groove has its surface ribbed transversely as clearly shown in Figs. 3 and 5. In the upper end of the wedge-shaped clamp 10 is arranged the socket 13 adapted for the reception of the extension 3 of the screw-threaded shank 2. An elongated nut 14 completes the device which is assembled as follows:

The elastic sides 6; 6, of the support are sprung apart as shown in Fig. 4, in order to admit the trolley wire. The projections 8,8,

are then brought together untilthe apertures 9, 9, register. The nut 14 is held underneath the lapping projections and the shank 2 with its projection 3 is passed down through the apertures 9, 9,and nut 14:. The wedge-shaped clamp 10 is slipped between the sides 6, G, of the support, its groove 12 resting upon the trolley wire 5. The extension 3 upon the screw-threaded portion 2 of the shank enters the socket 13 of the clamp, and as the shank is turned in positive rotation the engaged nut 14: is forced up against the apertured projections 8, 8, and the wedge-shaped clamp is forced down against the trolley wire, which is thus tightly gripped between the clamp and support, the ribs across the groove 12serving additionally to hold the wire and prevent the support from slipping thereon.

The extension 3 being seated in the socket 13 serves to prevent lateral displacement of the clamp.

It will be seen from the foregoing description that my improved clip or support is of simple and reliable construction and is. easily and quickly placed in engagement with the trolley wire or removed therefrom. Then too the ends of the bend 7 of the support are beveled off as at 15, (see Figs. 2 and 3) which offers an extremely slight obstruction to the trolley wheel as it passes thereby preventing its being thrown out of contact with the wire, thus avoiding any arcing at this point and insuring a constant action of the motor.

I am aware of a trolley clip or support comprising a long hanger extending along the top of the wire and a sheet-metal clip extending below the wire and clamped to the hanger at its ends, and I do not therefore lay claim to such construction.

I claim A trolley clip or support consisting of the elastic sheet metal support 6, 6, '7, its upper separate ends having apertured projections 8, 9, which register when the wire is in position and which can be pulled apart to admit the wire within the support, the removable wedgeshaped clamp 10 provided with the groove 12 Y in its lower side and the socket 13 in its upper portion the shank consisting of the upper,

annular shoulder 4 between the two screwv threaded portions 1 and 2 and the elongated nut 14 all combined and operating substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

FRED WM. HAEUSGEN.
